You are legally responsible for the actions of your agents. It’s in the name agent = acting on someone’s behalf.

Your English is very interesting by the way. You have some obvious grammatical errors in your text yet beautiful use of formal register.

[blibble]

in terms of "AI": agent is a marketing term, it has no legal meaning

it's a piece of non-deterministic software running on someone's computer

who is responsible for its actions? hardly clear cut

[Hizonner]

The person who chose to run it (and tell it what to do) is responsible for its actions. If you don't want to be responsible for something nondeterministic software does, then don't let nondeterministic software do that thing.

[SAI_Peregrinus]

The same as any other computer program: the operator of the program.
